tcp/mips: Change TCG_AREG0 (fp -> s0)
Register fp (frame pointer) is a bad choice for compilations
without optimisation, because the compiler makes heavy use
of this register (so the resulting code crashes).
Register s0 had been used for TCG_AREG1 in earlier releases,
but was no longer used and is now free for TCG_AREG0.
The resulting code works for compilations without
optimisation (tested with qemu mips in qemu mips
on x86 host).
